High elves play in all 4 phases - they all move well and have flyers and cavalry. They have some of the strongest magic and can get any of the 8 base lores + their own High Magic lore. The have good (light) shooting. Elite units fight well, both cavalry and infantry. They have monsters and beasts. They have armored units. The only disadvantage is their squishiness vs. their cost - they can die quickly.
I think they'd play way better than VC at low points - VC depends heavily on magic to regrow their losses and can just get hammered at low points with no way to come back.
Most of the HE units are a mix of male and female or are pretty androgynous. I haven't heard that the Sisters are particularly good, but if nothing else, there are a lot of female components for conversions and tons of female characters.
I don't play any of those though, so take it with a grain of salt. Hope to see you on Sunday! Bringing my almost-8-year-old, so it'll be a kidstravaganza!
